Leners Patent N 98,740, daten January 11, 1870.

IMPROVEMENT IN PUMPS.,

The Schedule referred to in these Letters Patent and making part of thesame.

To all lwhom it may concern Be it known that I, WILLIAM S. CARR, oi thecity end St-ate of New York, have invented and made a 4 new and usefulImprovement in Pumps; and I -do hereby declarethe following to be afull,clear, and exact description of' the said invention, referencebeing had to the annexed drawing, making part of this specitication,wherein- Figure 1 is a section, with part of the cylinder and -thevalve-box in elevation, and

Figure 2 is a vertical section, transversely, of the valve and box, atthe line x Similar parts are marked with the same letters of reference.y

This invention is intended especially for use in houses where the waterhas to be pumped up from a well or cistern, or elevated higher than thesupply, the pump being constructed with special reference to simplicityand easy access to the valves and packing's.

My invention] consists in an arrangement of valveseats, valves, andvalve-boxes, at one end of the pump, so that the induction andeduct'ion-valves come over each other .and communicate with water-ways,so as to make a double-acting pump, and I pack the pistonrod withdouble-cup leather washers facing each other, with a ring between them,so as toprevent water eserwin or airl assinv into thel um 3.

In the drawinga represents the barrel ofthe pump, supported upon asuitable stand, b, and

'c is a water-way leading from the rear along the side of thepump-barrel to near the head d, and opening into the pump at that point.

The rear end of the cylinder a is made with a box,

c, that forms, at its upper surface, the seats for the eduction-valvest', the same being formed from the leather that sits between thel box cand cap j, and this cap fis iitted, at its upper end,witl1 the couplingg, for the delivery-pipe.

rlhe box h is formed with seats lupon its upper snrftce for the valvesr. formed in the leather that sits between the boxes h and e, and theseparts arc'sethe screw-bolts lo passing through ears on f and h.

The box h is provided with the coupling I, for the induction-pipe, andit will now be seen that these valves sit upon seats that arehorizontal, or nearly so, and

each valve is of the ordinary character, with a leather face andweighted back.

The valves are easily cleaned or repaired by simply separating the'parts by removing the bolts 7c, and the valves are all close together,so as to be simultaneously put in order.

The division n separates the induction-ways to the front and back end ofthe pump as they extend into the box e. f

The piston of the pump is made with cup-leathers, sitting back to back,or in any other suitable manner.

The pistonfrod m is made with a jaw, o, at the end, with a roller in amortise, p, in the stock q.

p is the fulcrum, upon which the stock q is moved, by a lever, t,inserted ina socket at the upper end of the stock q.

The stuIiing-box for the rod 'in is made with cupleathers 2 and 3, setfacing leach other, and within the movable ring 4,

The anges of the cup-leathers coming at the endsprevented, and the saidcup-leathers are protected from injury by standing toward each otherwithin the. ring 4, and, acting in opposite directions, will preventwater coming out or air going into the pump.

A slight packing of elastic material, such as cottonwaste, might beinserted within the ring 4, and this packing is very tight, and, at thesame time, there is but little friction.

\Vhat I claim, and Idesire to secure by Letters Patent, is p,

l. The double cup-leathers 2 and 3, facing each other, and kept apart bythe ring 4, and clamped by tlIc'screw-cap n, and forming a packing forthe pistonrod nt, as and for the purposes set forth.

2. The aforesaid double cup-leather packing for the piston-rod, incombination with the double cup-leather piston, cylinder a, and valves'forming the pump, as and for the purposes specified.

In witness whereof, I have hereunto set my signature, this 31st day ofJuly, A. D. 1,869.
